Class DeferredPopupCommand

java.lang.Object
  org.cobogw.gwt.user.client.ui.DeferredPopupCommand

public class DeferredPopupCommand
extends java.lang.Object

This class is an extended version of the DeferredCommand class. This class will show a PopupPanel for the duration of the Command.execute() method. This will make it possible to provide easy user interactive feedback. For example showing a popup displaying the text 'Loading...'.

The class contains 2 addCommand methods. One that accepts a String and creates a PopupPanel with this String. The second accepts a PopupPanel and can be used to create a custom popup.

When using addCommand(Command, PopupPanel) make sure the popup is created with autohide set to false (This is default , but can be set). Otherwise the popup will disappear when the user clicks outside the popup.
